摘　　要：为了解决基于折射式光学系统的红外目标模拟器光束不平行度测量难题,提出红外五棱镜结合红外成像探测系统的测量与补偿方法。首先分析红外目标模拟器光束不平行度产生的机理,提出改进的红外不平行度测量方法,以及红外不平行度补偿方法。通过红外五棱镜在一维平移台的运动,将折射式或折反式模拟器光学系统出射红外光束翻转90°并实现光瞳的区域分割,红外焦平面探测器接收并测量运动过程中光点的偏移量,依此推导出红外目标模拟器光束的不平行度。经分析,测量结果满足红外制导仿真试验对光束不平行度1′的指标测试需求,适用于折射式光学系统的红外目标模拟器光束不平行度的现场测试。In order to solve the difficulty to measure the beam unparallelism of infrared scene simulator with transmission optical system,we propose the measurement and compensation method with the infrared pentaprism and infrared imaging detector in this paper.First,we analyze the mechanism of generation of the beam unparallelism of infrared scene simulator and propose an improved measurement method and a compensation method of the infrared beam unparallelism.By the movement of the infrared pentaprism on the one⁃dimensional translation stage,the direction of parallel beam from the infrared scene simulator is changed by 90°.The infrared imaging detector can receive the beam and measure the distance changed by the process of cutting the beam.This distance in the infrared imaging detector reflects the angel of beam unparallelism.The results show that the method can be used for the 1′beam unparallelism measurement requirement for the transmission optical system of infrared scene simulator in the application of infrared guidance hardware⁃in⁃the⁃loop simulation test.
